New pvp game mode

Disclaimer: Yes, I understand that each mode and mechanic is introduced for a specific purpose in the game or to perform a targeted action. However, it still feels a bit raw in my mind.

Idea:
A permanent PVP mode within the guild lobby. Let's say there is a space inside the guild where you can bring any squad you have. Any other guild member can practice on it.To prevent some players from becoming overpowered, you could limit it to one squad per player and three attempts to defeat them.

Every guild has 50 slots.
Everyone can make only three attacks.
